Abstract
A two component article of manufacture useful for removing paper adhered to a surface with a starch-based adhesive comprising a sealed moisture-proof first package containing an enzyme composition comprising either a carbohydrase or a carbohydrase and a protease and a second package containing a liquid comprising (a) an activator for the enzyme composition, (b) a wetting agent and (c) a solvent for reducing the rate of evaporation of water from paper. Paper is removed from the surface by mixing the contents of the two packages with hot water, applying the aqueous composition to the paper and removing the paper after the enzyme composition has degraded the adhesive properties of the adhesive.
